HOMlNY-MILL.

SPECIFICATION forming part of Letters Patent No. 313,337, dated March 3,1885.

Application filed June 12, 1884.

To all whom it may concern.-

Be it known that I, UAJUS O. JESSE, of Charleston, in the county ofCharleston, and in the State of South Carolina, have invented certainnew and useful Improvements in Hominy-Mills; and I do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, in which- Figure 1shows a perspective view of my hominy-mill with the hinged doors in thetop and side of one of the concaves shown open; Fig. 2, a similar viewof the mill from the'opposite side with one of the concaves turned downupon its hinges. Fig. 2 shows a detail plan view of the shaking-shoe andthe damsel; Fig. 2", a similar view of the receiving end of thefeed-spout; Fig. 3, a sectional plan view of the mill on the planethrough the bearings of the knife-shafts; Fig. 4, a detail view of oneof the shafts with its bearings; Fig. 5, a longitudinal sectional Viewof a portion of one of the shafts, and Fig. 6 a detail view in sideelevation of the end of the concave in which is situated thedischarge-spout; Fig. 7 adetail view of one of the knives. Figs. Sand 9are respectively detail views in elevation and section of a portion ofthe metal concave facing, and Fig. 10 shows a transverse verticalsection of the machine on line as x of Fig. 1.

Letters of like name and kind refer to like parts in each of thefigures.

The object of my invention is to provide an improvement in hominy-mills;and to this end it consists in the construction, arrangement, andcombination of parts, as hereinafter set forth, and more specificallypointed out in the claims.

In the drawings, A designates the frame of my mill, the ends of which, BB, are formed of the inwardly-inclined upright standards B B, connectedby the cross-beams b b b The frame ends are connected together by meansof the longitudinal side boards, 0 0, attached at each end to thestandards B B, and by the concave frame D, attached at each end to theinner sides of the frame ends by means of the upright boards D, fastenedto the cross bars b, b, and b Transverse bracerods 0 O are also used toconnect the side standards of the ends, and longitudinal rods (Nomodel.)

of sheet metal punched with square holes ff, 7

preferably one eighth of an inch square, punched alternately fromopposite sides of the sheet. The tops of the concaves are provided withstaples f f, which are engaged by hinged hasps f 2 f, attached to thetop beam, D of the concave frame to hold the concaves up in place.Wooden pins are passed through the staples to prevent the hasps frombecoming disengaged therefrom. The hasps are, as shown, riveted inplates f f*, which are screwed or otherwise fastened to the concaves.Each concave is provided with a swinging door, f on its side, andanother, f on its top.

These doors are for the purpose of allowing access to the rear oroutside of the concave faces F F, so that the concaves can be exam inedand cleaned or cleared, as desired or found necessary. Its bottom isleft open to allow the chops and. siftings passing out through theperforations in the metal facings of the concaves to fall downward uponan inclined apron, f which extends from side to side within the frame A,and serves to discharge the chops and sittings at one side of the mill,as shown. The inner and lower face of the top beam, D is formed like theinner face of beam D but with its sides inclined upward and outward. Theinner faces of both beams are covered with sheet metal.

The shafts E E are made of gas pipe or tub ing, as shown in thedrawings. Onto their ends are screwed the journals G G, cast withflanges G G, which come just within the ends of the concaves described.Bearings H H for these journals arev placed on the upper crossbars, If.Thesebearingsextendinwardthrough the ends of the concaves, so that theirends are close to the flanges on the journals, as shown. These flanges,situated as they are, will obviously prevent the corn being acted uponwithin the concaves from getting around the journals and interferingwith their free turning in their bearings. The shafts, as

shown, are parallel to each other, and revolve in the same direction.They are driven by means of the pinions I I, keyed or splined on theouter ends of the journals G G, which pinions mesh the gear-wheel K onthe shaft L, running the length of the frame and journaled at each endin bearings on the cross -ears b b. On the end of this shaft opposite tothat upon which gear-wheel K is fixed is the drivingpulley, which is tobe driven by a belt connection with any desired motive power. shafts E Eare each provided with three longitudinal rows of knives, N N.

In Figs. 4 and 5 I do not show the means of fastening the knifeshankswhich I prefer. In such figures of the drawings the shanks are shown asbeing fastened in the openings in the shaft by heading them down..

As the main object of these figures is to show the shaft itself and itsconstruction with its journals, I have shown the knives as fastened byheading for sake of clearness, as the shank-heads in these figures aretoo small to allow of proper showing of the form of fastening which Iprefer, as hereinafter set forth and described. These knives are setabout twoinches apartin my machine as constructed, and those on oneshaft are so situated as to project in between those on the other, theshafts being close enough together to cause the ends of the knives tooverlap each other, as shown best in Fig. 3.

The knives which I prefer to use are of the shape shownin Fig. 7,consisting of the shank n, upon the end of which is the two-edged bladen, enlarged from its point of attachment to the shanks to its end, so asto be fan-shaped. The shank is of sufficient length to extend entirelythrough the shaft to which the knife is attached; Openings are made inwalls of the shaft diametrically opposite each other for the passage ofthe shanks. Through the rear end of each knife-shank, at a pointjustbeyond the peripheral surface ofthe shaft, is an opening,0, adapted toreceive a wedge, O, which presses against the shaft-surface and servesto hold and fasten the knife-shank firmly and rigidly in place. W'iththis construction, if a knife becomes broken, it can be easily andquickly removed and replaced. If the operative edge of the knife becomesdulled, the wedge O can be slipped out and the knife can 'be turned tobring its other edge into action, and then be fi xed in place again bythe insertion and driving home of the wedge. Upon the upper beam of theconcave frame, at one end thereof, is supported the hopper-frame P, inwhich is supported the hopper R, below the dischargeopening of which isthe shaking-shoe P with a sloping bottom. As shown, this shoe ispivotally supported at one end, 1), so

as to allow of a rocking motion thereof as well as a rising and fallingmovement of the other end, 1). This latter end, in which is situated thedischarge-openingp,is supported by a cord, 1*, one end of which is tiedto the shoe and the other is tied to or wound around a pin, 1", on thehopper-frame. By this means the discharge end of the shoe can be raisedor lowered while being left free to vibrate and swing.

Journaled in a suitable bearing, 8, on the hopper-frame is thedamsel-shaft S,bearing on one end a pulley, s, and on the other adamsel, S, adapted to vibrate the shoe by its projecting angularportions or ribs coming into contact as it revolves with the side of theshoe or a projection thereon. A belt, T, runs over the pulley s and thedriving-shaft L. The speed of the damsel can beincreased or diminishedby changing the size of the pulley or by gear, as desired. Theshaking-shoe discharges into the feed-spout T, which is inclined to oneside, so that the material flowing through it enters the concave andruns down in the direction of the travel of that portion of the shaftand knives thereon which it first strikes. There will then not be atendency of the moving knives to throw the corn out and check the feed.The discharge-spout U is situated at the other end of the concave and onthe same side of the machine as the feed-spout opening through or intothe concave. The opening U through the concavecasing, through which thehominy passes and falls into the upper end of the spout, is regulated insize or closed by means of the sliding door or valve u, sliding in waysu at the sides of the opening. An ear or lug. u", on the back of thisslide is pivoted between the two ears a n on the end of rod 1; by meansof a pin, o,passing through it and such ears. The upper end of rod 12passes up through the 'concave-casing, and is screw-threaded, as shownat '0". Upon this screw-threaded portion is the thumb-nut or disktflturning in a slot, W, in the short standard or block w. As this nutor disk is turned the rod '0 will obviously be caused to move up or downto open or close the discharge-opening in the concave. In the disk areseveral openings, 10 w, adapted to be engaged by the end of hook w tohold the disk in any position.

The bottom of the spout U is made of wirenetting so that any fine dustremaining with the hominy as discharged from the concave will be siftedout and will fall down upon the apron f ,to be discharged by it alongwith the siftings and chops at the side of the machine.

With the inner casing or facing of the concaves, made of sheet metalpunched, as described, alternately from opposite sides, the

ings punched from the inner side of the metal facing. When one side getsworn, the sheet metal can be turned, and the other side thereof can thenbe used.

Having thus set forth the nature of my in vention, what I claim as newis 1 1. In a hominy-mill, the knife-shafts made of gas pipe or tubingand provided with journals screwed onto their ends, substantially asshown and described.

2. In a hominy-mill, the knife-shafts'made of gas pipe, in combinationwith journals screwed thereon and provided with flanges adapted toprotect the j ournal-bearings from the contents of the concaves,substantially as and for the purpose described.

3. In combination with the knife-shafts, the concaves hinged at theirlower sides to the frame and provided with means for locking them whenswung up into place, substantially as shown and described.

4. The concave provided with side and top doors to give access to theback of the concavefacing, substantially as shown and described.

5. The concaves faced with perforated sheet metal and provided with sideand top doors to give access to the back of the casing, and with an openbottom to allow the chops and sittings passing through the perforatedconcave facing to fall down and be dischargedbelow, substantially asshown and described.

6. In combination with the knife shaft, knives provided with shankspassing entirely through the shaft, and wedges passing through slots insuch shanks at or near their outer ends and bearing against the outer orperipheral surface of the shaft, substantially as shown and described.

7. In combination with the rocking shoe provided with a projection onits side, the damsel, the shaft on which the damsel is carried, thepulley on the damsel-shaft, the main driving-shaft, the pulley on thisshaft, and the band or belt passing over the two pulleys, substantiallyas and for the purpose described.

8. In combination with the casing havinga discharge-opening, the slideadapted to close or regulate the size of such opening, a rod pivotall yattached to the slide, ascrew nut or disk through which the rod istapped, and means, substantially as described, adapted to hold the nutfrom longitudinal movement while allowing it to be rotated, allsubstantially as shown and described.

9. In combination with the screw-threaded rod, the discharge-regulatingslide, thenut or disk on the rod, means for preventing the longitudinalmovement of the nut or disk while allowing it to turn, and means forlooking it, substantially as shown and described.

10. The facing for the concave of a hominymill, formed of sheet metalhaving holes punched through it alternately from opposite sides,substantially as shown and described.

11. A facing for the concave ofa hominy mill, consisting of a sheet ofmetal having square holes punched through it from opposite sidesalternately, substantially as and fo the purpose described.

In testimony that I claim the foregoing I have hereunto set my hand this11th day of 70 March, A. D. 1884.
